| 中文摘要:在河南省驻马店汝南县林楼一正阳县张楼一带的煤田勘探中，第三、第四系地层厚达700m，经常遇到水敏性粘土、砂质粘土、砂质泥岩、粉砂岩和卵砾石等地层，易造成缩径、超径、坍塌和掉块等孔内复杂情况。结合该地区的地层特征，采用新型LG植物胶泥浆来解决钻探的“瓶颈”难题。应用实践表明，LG泥浆起到了显著的抑制缩径、超径和防塌作用，大大减少了孔内事故的发生，提高了钻进效率。 |

| Abstract:In coalfield exploration in Runan County of Henan Province,thickness of tertiary and quaternary formation is up to 700 m,water sensitive clay,sandy clay,sandy argillite,aleurolite and gravel strata are often encountered.These easily cause hole diameter's shortage or enlargement,wall of hole collapsing and breaking.According to the strata feature,LG plant glue mud was chosen to solve these difficult problems.It is proved by application that LG mud obviously controls hole diameter's shortage or enlargement,wall of hole collapsing and breaking,greatly reduces borehole accident with drilling efficiency risen. |
